Key value for chemical safety assessment

Additional information

No data are available for anhydrous ammonia. This endpoint is waived in accordance with Column 2 of Annex VII of the REACH Regulation as the substance is a gas at room temperature.

The surface tension of aqueous ammonia solutions is dependent on solution strength and is reported to be between 71.65 to 57.05 dynes/cm for a solution of ammonia with a concentration of 1.72 to 54.37 %wt in water (Chemical Engineer's Handbook).
